Visual Basic :: Disabling MDI Child Form Resizability

Urgent Help - TreeView Enabling/Disabling Child Nodes
I'm trying to load a treeview that has upto 4 levels. The requirement is, while loading the treeview, i need to enable the Level 3 and level 4 and disable the rest.
I know that we have Treeview.enabled = false but is it possible to use this at various levels.

Root
Parent1
    AA
    BB
        BB1
            BB12

In the above, i need to enable bb1 and bb12 and disable the rest. Also, is it possible to show the treeview as expanded with the selection that was already made.
be it that im loading the treeview in a View mode where the user has already made a selection of BB12. Can the treeview be expanded while loading the second time based on the mode?

Pls provide inputs.

(RESOLVED)make Mdi Child Regular Form And Then Back To Mdi Child?
I have a MDI parent form that loads several children based on which button on a toolbar the user selects. I also want to provide a menu for the user to view each form individually outside the parent form as a regular form. Is it possible to do? Why? Well in a previous version of my software, users had to select each form individually to update information. I am enhancing the software so that they can update any of the forms in the same place by using mdi parents and children. However, some users are used to the old way and still want that as an option. But when I call the new forms, they load inside the parent form. Help anyone???

Child MDI Form Close - Other Child Forms Repaint/bleed
I have an application that has multiple Child MDI forms.

when one of the child forms are unloaded (by user or by code), another child form becomes 'active' and it repaint's itself.

During the time it takes to repaint, it looks like it resizes it selft, and the outlines of controls (mhtree, etc) appear like ghost windows on the form.

I've tried using LockWindowUpdate, but it doesn't seem to do anything.

Does anyone know what can be done to stop the form from 'ghost painting' itself?

Thanks,

Earl

MDI Form With Child Forms - External Form/window To Interact With Child Forms?
Hi,

I am creating an application which has an MDI Form containing 2 child forms.

I need to somehow create either a floating toolbar or some sort of external form (ie. not a child form) which is able to interact with the child forms.

Is this possible? If so, any feedback on how to create it would be much appreciated

Disabling The X Icon In A User Form To Prevent Closing A Form From There
Hi,

How do I disable the X icon on the right top of a form, so that the user cannot close the form in this way ?

Disabling All Form's Control Or The Form Upon Opening The Form.
Hi There

Here is my Objective (What I want to accomploish).
Upon opening a Form Called “Search”, the Curser gets focused on a ComboBox called “comboTrans”, And the user must select a value form the ComboBox before they are allowed to move to any other Control. (That is all)
Off Course since the form is an Unbound, They should be able to close the Form any time they wish, Even thou, they have not selected any value from the ComboBox “comboTrans” yet.

I tried many different events of The control and the form itself.
The closest that I came to reach the above objective was in Lostfocus Event of the control itself, But It causes problem when the user decides to close the Form before entering any values ‘for any reason”, the Control’s msgBox Keeps Popping Up.

Therefore I decided a different technique;
And that is Upon Opening the Form, Basically disable or Lock all the controls in the above Form or the Form itself, Except the ComboBox. Then setting the focus on the Active ComboBox, and Even if the User moves to other control, with the help of a MsgBox Forcing the user to move back and select a value from the Active ComboBox
And in the AfterUpdate event of the ComboBox make all other controls Enabled or active again.
A note the form has No record Source and the Control itself is unbound and has No Control Source.

Best Regards

Returning A Value Found In A Child Form To A Specific Text Box In The Parent Form?
I have two forms. A parent and a child. The parent has many labels which are selectable. Once one of the many lables is selected, a child form pops up to gather info. Once the info is gathered, i want to be able to put that info into the label in the parent form which called the child! How can this be done? The problem i cant get past is when the child returns, i have no way to know which label called the child in the first place to put the info in.

Thanks in advance

Call The Save Method Of An MDI Child Form From The MDI Form Toolbar Menu Caused Error
Hi all,

This step-by-step article 818367 describes how to call the Save method in a multiple document interface (MDI) child form when you click the Toolbar button on the MDI Form.
However, execute statement <Me.ActiveForm.cmdSave_Click> ended up with error saying "Object does'nt support this property or method". Please advise and appreciated.

1. Start Visual Basic 6.0.
2. On the File menu, click New Project. In the New Project dialog box, click
Standard EXE, and then click OK.
3. In Solution Explorer, right-click Form1, and then click Remove Form1.
4. On the Project menu, click Add MDI Form.
5. In the Add MDI Form dialog box, click MDI Form, and then click Open.
6. Set the Name property of the MDI Form to frmMDI, and then set the
WindowState property to Maximized.
7. On the Project menu, click Add Form. In the Add Form dialog box, click
Form, and then click Open. By default, the Form1 form is created
8. Set the MDIChild property of the Form1 form to True, and then set the
Borderstyle property of the Form1 form to Fixed Dialog.
9. Add a command button and a text box to the Form. Set the Name property
of Command Button to cmdSave, and then set the Caption property to
Save.
10.To view the code editor, double-click the Save command button. Change
the Click event scope of the cmdSave event handler from Private to Public.
11. Repeat step 5 through step 8 two times. This adds MDI child form Form2
and MDI child form Form3.
12. Add the following code to the Click event of the Save command button of
the MDI child form Form1:MsgBox " Save event of MDI Child Form: Child1"
13. Add the following code to the Click event of the Save command button of
the MDI child form Form2:MsgBox " Save event of MDI Child Form: Child2"
14. Add the following code to the Click event of the Save command button of
the MDI child form Form3:MsgBox " Save event of MDI Child Form: Child3"

Insert Button to add a Toolbar button. Set the Caption property of the
Toolbar button to Save, and then set the Key property to Save.
18. Click OK.
19. To view the code editor, double-click the Toolbar to open in Code view.
20. Add the following code to the Click event of the Toolbar:
On Error GoTo NoActiveForm
Select Case Button.Key
Case "save"
Me.ActiveForm.cmdSave_Click
End Select
Exit Sub
NoActiveForm:
MsgBox Err.Description
21. Add the following code to the Load event of the MDI Form frmMDI to
show all the MDI child forms when the application starts.
Form1.Show
Form2.Show
Form3.Show
22. On the Project menu, click Project Properties. In the Startup Object
combo box on the General tab, click frmMDI as the startup object.

Disable Resizing Of MDI Child Form && Creating Form Icon
I have two things that I want to do: -

1) How do i disable the resizing of a MDI Child/Parent form when my application is run. For example when the program is being run I want the size of the forms to remain the same size all the time, in order to do this the user should not be able to resize the forms.

2) What is the best way to create my own customized icon to put on a form? and how do i change the colour of the Forms caption bar (the bar where the icon resides on the form).

Any help will be much appreciated

How To Change Properties Of The Parent Form From A Modal Child Form, Plz?
I want to open a child form windows (frmPortSetting) and from there changing some ActiveX components properties (comTx) which are on my parent form (frmMain).
I wrote code in frmPortSetting sub procedure but it seems that I can't change comTx properties directly there. (e.g. comTx.settings(9600,n,8,1)) Any advise please?

Accessing A Unique MDI Child Form When There Are Multiple Instances Of The Same Form ???
In the application multiple MDI child forms are created as needed. An example is as follows:

Code:Private Sub LoadNewDoc()
    Static lDocumentCount As Long
    Dim frmD As frmDocument
    lDocumentCount = lDocumentCount + 1
    Set frmD = New frmDocument
    frmD.Caption = "Document " & lDocumentCount
    frmD.Show
End Sub

Say that frmDocument contains some subs that I want to call from a different location and multiple instances of this frmDocument are currently in existance. I would like to execute a sub from one of these already existing forms.

I don't know how these forms are uniquely identified to address one of them. I know that the hwnd is unique when they are created but I don't know how to use that for what I want to do. I am imagining an API thing using the hwnd value? I don't want to search all the forms' captions to find the one I want - too slow for what is required - just want to directly access a particular instance of the forms subroutines

Can anyone help?

Disabling F10 When Form Unloads
Hi,
I have this application when f10 is clicked it opens its own menus probably thru hotkey. Ive managed to position this app on top of my interface when a button is pushed. But when the button is released this application is then hidden and you could open other windows and stuff on the interface. But when f10 is clicked, it opens up that application menus. So I want to disable the f10 key when Ive hidden the application therefore it wont show when I look at other menus on my interface and if the user does not accidentally press f10. Ive found some threads on disabling ctrl-alt-del using registry. Should I be doing the same for function keys?
Or is there another way?

Thanks

Disabling Max Button In An MDI Form
Hi,

I'm trying to disable the maxbutton in an MDIForm.

The following code removes the max menuitem and causes the maxbutton not to maximize the form when clicked. But it still looks as if it is enabled. When I do the same for the close (x) button it does look disabled.
How do I disable the maxbutton so that it also looks disabled.

Code:
Option Explicit

Public Declare Function GetSystemMenu Lib "user32" (ByVal hwnd As Long, ByVal bRevert As Long) As Long
Public Declare Function GetMenuItemCount Lib "user32" (ByVal hMenu As Long) As Long
Public Declare Function RemoveMenu Lib "user32" (ByVal hMenu As Long, ByVal nPosition As Long, ByVal wFlags As Long) As Long
Public Declare Function DrawMenuBar Lib "user32" (ByVal hwnd As Long) As Long

Public Const MF_BYPOSITION = &H400&
Public Const MF_REMOVE = &H1000&
Public Const MF_ENABLED = &H0&
Public Const MF_INSERT = &H0&

Public Sub DisableMaximize(frm As MDIForm, blnEnable As Boolean)
Dim hMenu As Long
Dim nCount As Long

If Not blnEnable Then
hMenu = GetSystemMenu(frm.hwnd, 0)
nCount = GetMenuItemCount(hMenu)

'Use cCount -1 to disable the closebutton
Call RemoveMenu(hMenu, nCount - 3, MF_REMOVE Or MF_BYPOSITION)

DrawMenuBar frm.hwnd
Else
hMenu = GetSystemMenu(frm.hwnd, True)
DrawMenuBar frm.hwnd
End If

End Sub

'In the midform
Private Sub MDIForm_Load()

Call DisableMaximize(Me, False)

End Sub

Open A Child Form At The Same Record As Its Parent Form
I am trying to open a child form from a parent form, say the parent form is on record number 20. 20 is the ID number for the record. I want the child form to then also move to record number 20.

These forms are of the same table data, I just want some of the data displayed on the child form top avoid congestion.

I've looked at DoCmd.GotoRecord and DAO options. I think an ADO option is too complicated for just form data.

Thanks in advance for any help you can provide.

***RESOLVED***MDI Child Form Placement In Parent Form
I am using the MDI Parent/Child forms in my project.

I have one of my child forms open. On this child form is a command button which opens a second child form. I would like it if when the second child form is opened, it opens directly below the first child form. It would also be great if it would open below the first child form regardless of where the user has moved this form on their screen.

Displaying A Child Form Without Parent Form In Backround??
I want to create a form that behaves just like Outlook mail notification. I have an application that I want to display a notify form that something has happened. I want this notify form to display centered and topmost. Once the notify form is front and center I want the ability to act on it or select another application to have notify form disappear or minimized showing it on the taskbar. Then when I select the notify form from the taskbar, it will show but NOT have my parent application show.

I can set the form on the top and have it centered. I just need help with the rest.

VB6 MDI Form 'bleeds' When Child Form Loaded Or Unloaded
Has anyone come across this?

I've scanned microsoft KB and here and a few other places, but no one seems to have come across this... either that, or I'm not searching for the right words...

When my program displays or unloads child forms in a MDI form, the controls are painted one at a time, and the borders of the controls look like they 'bleed' through, until everything is painted.

I've been using the LockWindowUpdate function to control some of this, but in certain cases, it doesn't seem to have an affect.

Does anyone know if there is a solution for this problem? The original program was converted from VB3 if this has anything to do with it..

Thanks,

Earl

Enabling/disabling Many Items On A Form
I'm very new to VB, in this case within Access, and I'm a little mystified about how to complete one task. I'd like the majority of the fields and buttons on a form to go "read only" (disabled) when the selected record (part of an order) is "filled". Basically I would like to wire the fields to a method on the form that returns a bool saying whether or not that field should be enabled.

I can't see to see how to do this. The system currently allows me to set the enabled property only as Yes or No. What I want is to set it to my "shouldBeEnabled" function. Is there a way to do this?

There is a fairly similar function I would like to build to allow each field to display a colored border, red for things that need to be filled out and are currently empty, yellow for things they don't need to fill out but should, etc. For this task I would want to have a sub for each field that returns a color, but again it seems that that color can only be set to a fixed value.

Thanks!

Disabling The Print Form Button
Ok, here is the question. I have a calculate button, a clear button, a print button and a exit button. I have text boxes and other things. But the Print Form button will be available only after the calculation has been made--it will be disabled until the Calculation button is pressed the first time. When the clear button is pressed,the Print Form button will become disabled. The properties I have set now are: Print button enable property is False, default property of the calculate button is True, cancel property of the Clear button is True. My teacher gave us these hints to set the properties. Teacher also wrote: In the code for the calculate button, set the enable property to true for the print button, and in the code for the clear button, set the enable property to false for the print button. Can somebody please help me? I have tried to do this for 4 days now and I am stumped. Thank you very much. You can e-mail me at toykoon@aol.com if you like. Thanks......Scott
